The developers of Bayonetta have admitted the game was initially developed for the Xbox 360, and that there will be “differences” between the versions, leading some to worry that an inferior PS3 port is in the works…

They admit developing the game exclusively for the Xbox on their blog:

“We developed this initially for the Xbox 360, later giving all the game data to Sega for them to develop a PS3 version; we then advised them and supervised their development of the PS3 version.”

Unusually, the developers admit openly that the two versions will be “different” (and previously the versions were said to be the same):

“With the differences between the 360 and PS3’s hardware, of course differences will emerge, but I hope everyone will be able to see for themselves that we have adapted each version’s code to the peculiarities of the hardware in question.”

The suspicion is that the game will be superior on its original Xbox 360 platform, as the PS3 version shown so far was said to have very noticeable performance problems, and is apparently not even being handled in-house.

Just why an Xbox “exclusive” could not be secured is an open question…

This deserves only to be on the xbox, since you ps3 fanboys already got your ninja gaiden sigma 2, good thing comes to those who wait, and i dearly say us xbox fans has waited for this game. it's fair enough from my point of view. :D hahahaha.

It won't be "secured" because SEGA has been on red numbers for quite some time now (they enter and quit this state of affairs quite frequently), and a crappy PS3 port job can easily recoup the additional development costs and then some.

And hey, there's also a chance that Final Fantasy XIII will be better on the 360, too!! http://www.eurogamer.net/articles/final-fantasy-xiii-how-will-it-work-on-360-article

WoW...fanboy site much? They said its because of the hardware differences and the game was written originally for the 360 and thats why it would get messed up, but these articles are all like "360 won!HAH!" you box fanboys too lol, they are both fairly shitty in their own way, but Ps3's hardware is superior to a 360s, you box owners still have a shit piece of hardware :P, there's no reason Live can't be fully executed for PC users... ohwait I use live right now to play DoW II an SFIV...unfortunately..its a piece of shit as well :/

when i play the bayonetta demo on my ps3 all i can think of is wow...i can play this game and not have to send my system in every 4 months because of over heating issues. But in fairness you box boys have...halo...

Phah! the 360 alway's had the "GOOD" games, ps3 was brought out to late and the wii is for kiddies and the elderly! WHOOP WHOOP and besides boy's this game is really good and i want her outfit!! Yay for female super hero's

SEGA HATES SONY!! IT'S SO APPARENT!!
Do you guys ever remember the previous generation of console wars? How does SEGA loose miserably?
And they will find whatever reasons to justify their acts against SONY. We can expect even more & more similar things happened if any make hand in their games to be ported by SEGA.

Maybe they ought to delay the PS3 version until they can release a PS3 version that's at least fairly comparable to the 360 version.This has been happenig more and more lately and i seriously wonder why bother with the PS3 version if that version will be admitedly subpar compared to the 360 version.In the end all that does is cause biterness from those that buy the inferior version thinking they are getting the same game available on the other system.Unfortunately not everyone reads reviews or lurks sites like this.

They're headed up (and staffed) by of some of Capcom's best ever talent, who left the company after Clover Studio was closed. People responsible for Resident Evil, Devil May Cry, Viewtiful Joe, God Hand and Okami.

Regarding the last comment of the article, most multiplatform games are developed for one platform then ported to the other(s). And for the most part, due largely to the worldwide installed base, the first platform this generation is the Xbox 360.

Bayonetta was likely never intended, or pushed by either platform holder considering the relatively niche appeal of Platinum Games' output to date, to be an exclusive.

Im a programmer at a studio that mostly does multiplatform stuff. What you said is right, but usually the "porting" starts early.

There's always a "lead platform" where the features and bugs are first implemented, but the porting (or rather "maintaining the other builds" can begin during production already). It's rather risky to start the other versions late.

But, it's true that during production one version will always be ahead of the others in terms of bugfreeness and features.

I mean, I'd rather have a limited time 360 exclulsive, and then get "Bayonetta: We Had Time To Actually Make Use Of The PS3 Edition". OMG and it can magically have Dante and Amaterasu as guest characters!

I find this quite ironic. On one hand there are developers using the xbox 360 "exclusivity" to make a far superior PS3 version of the game, while on the other hand there is the developers making "multi-platform" games that are easier to code on the xbox 360 while having problem on the PS3.
Either way, the PC version will always be far superior than the console version as there will always be the "nude patch" available, hahaha...

Exclusive is because it's a third party developer, they can contract and put whatever game they're making on whatever console they wish as long as they have permissions from that company. And performance issues? I wish someone would outline the issues so we all can understand what's going on.
